ROOFING-TILE.

SPECIFICATION forming art be Letters Patent No. 283,126, dated August 14,. 1883.

, l Application filed December 1 l, 1882. -(No model.) Patented in Germany May 7, 1881. No. 16,757,, and September 4, 1881, No. 17,940;

. To all whom it may concern.-

Be it known that I, WILHELM LUDowIoI, of Ludwigshafen-on-the-Rhine, Germany,have invented new and Improved Roofing-Tiles, of

i 5 which'the following is a full, clear, and exact description. v

The objectof mfinvention is to provide new and improved roofing-tiles, which form very close joints, conduct off all water, and cannot be raised by wind, prevent the wind from driving the rain through the joints, are very light and durable, and can be attached to the roof very easily.

The invention consists in details of constru ction, as will penny described hereinafter. 1 Reference is to'be'had-to the accompanying drawings, formingpart" of this specification, in which similar letters-of-reference indicate corresponding partsinall the figures.

Figure l is a face -view of one of my improvedroofing-tiles. Fig. 2 is a longitudinal elevation of the ame, parts being shown in section. of the same. Fig. 4is across-sectional elevation of a series of thesame. Fig. 5 is adetail longitudinal sectional elevation of the same, show ing the end joint. Fig. 6 is a detail cross sectional elevation of the same, showing the side j oint. Fig. 7 is a transverse section through line m of Fig. 1. Fig. Sisa view in elevation of the bottom end of tile.

The tile A is providedin its upper surface with two longitudinal grooves, B, which may be segmental in cross-section, or may be formed of two segments, as shown, which grooves are separated by a longitudinal central ridge, (1, which does notproject above the levelof the upper surface of the tile. Thetwo parallel grooves B are curved toward the middle rib, C, so as to cause thefsnow and water to slide off very rapidly, the snow finding no ing corners against which it can rest. At its upper end the tile is provided in its upper surface with a transverse groove, D,

tile. The grooves D E form a transverse end,

ridge, F, and a transverse ridge, G, between othe two grooves DE.

On the underside of the :tile a transverse Fi 3 is a plan view of the under side project and adjoining the same with an additional;

ridge, H, is formed a short distance from the upper end, which ridge rests against the upper longitudinal edge of the roof-slat J, for the purpose of holdingthe tile on the roof. The

,grooves B extend from the lower end of the tile to the lower edge of the groove E at the upper endof thetile; The ridges F and G do not project above the level of the-upper surface of the tile.

At the lower end the tile is provided in its under surface with a transverse-ridge, K, and

with a ridge, L, parallel with and ashort distance from the ridge K. The upper surface of the tile is rounded off toward the ridge K at the lower end of the tile. The right and left hand ends of the 1 i dge 1 are rounded to fit against the ridge a, for the'tiles are arranged with broken JfQintS', the joints of one row of tiles paralllwith the peak of the roof coming over the centers of the upper ends of the next lower row. The ridge K of one tile passes into .the transverse groove E of the next lower tile and the ridge Lpasses into the groove D of the said next lower tile, as shown in Fig. 5. a r

In its upper surface the tile is provided along its edge withther groove M and rabbet M, forming a ridge,.dl, a short distance from a the said edge, and 'a lip, O, in the said edge. A rabbet, P, is formed in the inner edge or rside of the groove M. In its under surface the tile is provided along the opposite longitudinal edge with a groove, Q, and a rabbet, Q, forming a ridge, B, a short distance from 8 the edge, and a lip, S, in the said edge. The inner edge or side of the groove Q is provided with a rabbet,*T. At the longitudinal edges the tiles overlap each other; as shown in Fig.

6, the ridge R passing into the groove M and 0, the ridge N intothe groove Q, and the lip S overlapping' the rabbet P and the lipO the rabbetT. The water thatpasses into the transverse or longitudinal joint-grooves can all flow off, and as all joints are double the wind can 5 not blow the'water through the joints. The longitudinal grooves B B form a series of gutters from the ridge to the eaves of the roof.

The side joint grooves are arranged to give the tiles the required play. As the surface of roo i the tiles are curved, the tiles can be made very thin and light, and will yet be very durable.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1'. A roofing-tile having the channel E, with a half-round rib, a, and a correspondingly corner-recessed head, K, as shown, whereby the tile may rest with its entire width on the roof and be securely held against storms or wind.

2. A roofing-tile provided with the grooves M and Q, rabbet' M and Q, and the ridges N and R at the longitudinal edges, substantially as herein shown and described, and for the purpose setforth.

3. A roofing-tile provided with 'the grooves I 5 M and Q, the ridges Nand R, the rabbets T, Q, M, and P at the longitudinal edges, substantially as herein shown and described, and for the purpose set forth.
